ETHOCEL™ Standard 300 Industrial is the largest molecular weight ethyl cellulose polymer available from DuPont. It is soluble in many common solvent types including ketones, alcohols, esters, and ethers. It is primarily used as a pseudoplastic rheology modifier and thickener for solvent based inks and coatings. ETHOCEL™ Standard 300 Industrial is also useful as a binder to improve green strength in applications that require high purity and clean burn out like conductive pastes for screen printing circuits. Additionally, ETHOCEL™ Standard 300 Industrial is thermoplastic and can be used as a film former or resin modifier to improve film strength and flexibility in coatings, inks, and adhesives. It is compatible with many common plasticizers and it can be dissolved in hot polymers and waxes. When used in heat seal applications ETHOCEL™ Standard 300 improves bond strength, flexibility, and moisture resistance.
